Also thank you for explaining Polar Covalent bonds so clearly, I'm now looking at Mendelevs periodic table in a whole new way and it makes sense. I now understand how these molecules come together and function the way they do

Dear Mr Phillips just to make it absolutely crystal clear in my mind if, for example in a haploid gamete I have chromosome 1a all thst it contains are alleles?Now if I take another haploid cell containing chromosome 1b that contains the same allele or an alternative allele, these two haploid cells come together to produce an offspring, will those two alleles produce a gene?Do you get just half your alleles from one parent and the other half from your other parent and then those alleles produce your genes?If this is correct then thank you so much, because I have spent quite a while trying to find this answer.Thank you so much Doctor Philips you are a superb teacher

Structure of Proteins

Medium, 6 examples, 5 practice questions

Proteins are macromolecules made up of amino acids connected by peptide bonds.

21 different amino acids are commonly incorporated into proteins, including selenocysteine.

Proteins can be organized into four degrees of higher order structure.

Three-dimensional structure often dictates the function of proteins.

Some proteins, called enzymes, can catalyze biochemical reactions.

Structure of Proteins

Ester

Hydrophobic

Which of the following has no net charge at a physiological pH of 7.4?

Isoleucine

Aspartate

Lysine

Histidine

The sequence of amino acids, connected by peptide bonds, is what level of structure?

*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
